Spatial variability of compacted subsoil depth: a combination of field observation, electrical resistivity tomography and X-ray computed tomography
Original language description
The aim of this contribution is to present the results of the monitoring of the plough pan depth spatial distribution at the experimental catchment Nucice (Czech Republic) done by means of soil penetration resistance testing, etelectrical resistivity tomography and X-ray CT scanning. To observe the divide between topsoil and subsoil layers in detail and to be able to compare the soil structure and pore networks of both layers we inspected undisturbed soil samples with X-ray computed tomography. The divide between the conservatively tilled topsoil and the subsoil is clearly observable also directly in terrain. To identify its exact position we implemented a combination of penetrometry, soil sampling and electrical resistance tomography (ERT). The penetration tests accompanied by soil probing were done in an irregular network across the whole catchment based on the slopes and distance to the stream.
